Web-design blog Bittbox just released 72 cool-looking glass-effect buttons and bars you can add to your web site.

The collection is provided in vector format, meaning you can scale them as necessary and not have to worry about pixelation. If you want to customize the images, you'll need a graphics editor like Adobe Illustrator. The buttons and bars can be downloaded in Illustrator, EPS, PNG, and SVG formats. They're free of charge to use, as are various other slick design elements available on the Bittbox site. You should definitely poke around. — Rick Broida
